Sea Shepherd Conservation Society. The Sea Shepherd Conservation Society (SSCS) is a non-profit, marine conservation organization based in Friday Harbor on San Juan Island, Washington in the United States.[1] Sea Shepherd uses direct action tactics to protect marine life.

The organization was founded in 1977 under the name Earth Force Society by Paul Watson, a former member of Greenpeace, after a dispute with that organization over what Watson saw as its lack of more aggressive intervention.[2] The group has a strong focus on public relations to spread its message via the media.
Piracy. Piracy is typically an act of robbery or criminal violence at sea.

The term can include acts committed on land, in the air, or in other major bodies of water or on a shore. It does not normally include crimes committed against persons traveling on the same vessel as the perpetrator (e.g. one passenger stealing from others on the same vessel).
Piracy in Somalia. Map of areas under threat by Somali pirates (2005–2010). A United Nations report and several news sources have suggested that piracy off the coast of Somalia was caused in part by illegal fishing.[6][7] According to the DIW and the U.S. House Armed Services Committee, the dumping of toxic waste in Somali waters by foreign vessels also severely constrained the ability of local fishermen to earn a living.

In response, the fishermen began forming armed groups to stop the foreign ships. They eventually turned to hijacking commercial vessels for ransom as an alternate source of income.[5][8] In 2009, a survey by WardheerNews found that approximately 70 percent of the local coastal communities at the time "strongly support[ed] the piracy as a form of national defense of the country's territorial waters".
